IMPROVED MEAT-.CUTTER 'fhe Schedule referred to in these Letters Patent Aand making part of the saine.

To aZLwhom-z't may concern:

, Beitknown thatV 1,0. I). `WOODRUFF, of Southingt0n, in the ,county of Hartford, and State'of Connecticut, have' invented a new and useful Improvement in Meat-Outters;jand I do hereby declare that the follow- :ing is a full, clear, and exact description thereof, which will enable those skilled inthe art to make and use the same, reference being had to the accompanying drawings,- m'aking'a part of this specification, in whichl' Figure 1 is a plan or top view of my invention, with theupper portion of the shell or case removed.

Fignr`e'2 is aside elevation of thesha-ft.

Figure 3 is a side elevation of one of the knives.

Figure 4 isa side elevation of one of the drivers.

Figurei is a `transverse sectionlon line x-y;

Similar' letters of reference indicate like parts.

My inventionconsists in the use or employment of arms, or studs, projecting from a revolving shaft or cylinder', and combined with a set of knives on the same shaft, as hereinafter described.

a designates the arms, or studs, which I term the drivers.

c designates the knives.

i Both' the knives c and driversn are arranged spirally on the same shaft, with the front of each driver a -a little -back of the cutting-edgeof each one of the knives c.

' The shell, or case, IA, is substantially the same as those in common use, and has stationary studs, (l, cast on one part of the case A.

The stationary studs d should be of such distances apart as to allow one of the drivers a and knives c to pass freely between the same.

Immediately after the meat is' cut by each knife c, the driver L strikes the meat, and Carries it on, clearing the stationary studs d of meat, ready for a fresh supply, thereby greatly hurl-ying the meat in its passage through the mach-ine.

These drivers a can be combined lwith 'knives .on'

any revolving shaft,in any of the ordinary styles of meat-cutters, and will be found very advantageous in crowding the meat in its passage through the maf chine.

I construct the shaft B round, and with a spiral groove, e, as shown in 'dg. 2.

Near the centre of the knives c and drivers a,.I make a round aperture with a small spur, i, extending toward its centre.

On one end of shaft B, I place a pin, m, or a suitable flange, and the other' end of said shaftis threaded t0 receive the nut n.

As the knives cand driversa are placed on the shaft B, the small spurt' enters the spiral groove e, and causes the knives c and drivers a to maintain a spiral form on the shaft B. The 'whole are then secured in place by thenut n.

What I elaimjas new, and desire to secure by Letters Patent, is

Thedrivers a and knives c, when combined and arranged alternately on the same shaft, substantially as shown and described, and for the purposes set forth.
